Abstract
The utility model discloses a pipeline pressure control device arranged in a natural gas well. The pipeline pressure control device comprises a vortex-type compressor. A frequency converter or a communication server is connected with the vortex-type compressor through an electromotor. One end of the vortex-type compressor is a gas inlet and the other end of the vortex-type compressor is a gas outlet. A single-way valve is arranged between the gas inlet and the gas outlet. An inlet pressure transmitter is arranged at the inlet of the vortex-type compressor and connected with the frequency converter or the communication server. An overpressure protection device is arranged at the outlet of the vortex-type compressor. According to the pipeline pressure control device, all gas wells do not affect each other even the pressure of all gas wells is different, quantity of production in extracting natural gas is improved and safety accidents are avoided.
Description
Technical field
The pipe pressure controller that the utility model relevant a kind of pipe pressure controller, particularly a kind of natural gas well are used.
Background technology
Rock gas often has a plurality of gas wells simultaneously in exploitation, the rock gas of a plurality of gas well extraction is imported in the manifold jointly by many pipelines, then is transported to the user place.But because each gas well pressure of giving vent to anger is different, has caused at the gas well of manifold place low pressure and can't export gas, even gases at high pressure may occur poured in down a chimney into low-pressure gas well, not only affected the output of natural gas extraction, and easily caused danger.
Summary of the invention
The utility model provides a kind of pipe pressure controller, to solve the different technical matters of each gas well pressure that exists in the background technology.
A kind of pipe pressure controller of the present utility model is installed in the natural gas well for this reason, comprises scroll compressor, and frequency converter connects described scroll compressor by motor, and described scroll compressor one end is the gas access, and an end is outlet.
Wherein, between the described entrance and exit retaining valve is installed.
Wherein, described scroll compressor porch is provided with the inlet pressure transmitter, and described inlet pressure transmitter links to each other with described frequency converter.
Wherein, described scroll compressor exit is provided with over-pressure safety device.
The utility model so that do not interact because of the difference of pressure between each gas well, has improved the output of natural gas extraction by technique scheme, avoids occuring security incident, has reached useful technique effect.

Fig. 1 is structural representation of the present utility model.
Description of reference numerals
Scroll compressor-1; Entrance-11; Outlet-12; Motor-2; Frequency converter-3.
Embodiment
For shape of the present utility model, structure and characteristics can be understood better, below will enumerate preferred embodiment and also be elaborated by reference to the accompanying drawings.
Pipe pressure controller of the present utility model is installed on the natural gas well well head, and its structure comprises scroll compressor 1 as shown in Figure 1, and frequency converter 3 connects scroll compressor 1 by motor 2.Scroll compressor 1 one ends are that entrance 11, one ends are outlet 12, and gas enters from this entrance 11, flow out from this outlet 12 after this scroll compressor 1 pressurization, reach the effect that promotes gaseous tension in the gas well.Entrance 11 and export 12 between retaining valve is installed, avoid gas to pour in down a chimney and when wellhead pressure is high, shut down, guarantee that gas well is kept to give vent to anger.
Scroll compressor 1 entrance 11 places are provided with the inlet pressure transmitter, and described inlet pressure transmitter links to each other with frequency converter 3, and the pressure signal transmission of entrance 11 place's gases to frequency converter 3, is realized the automatic control of 3 pairs of pressure of frequency converter.When entrance 11 place's gaseous tensions are higher, frequency converter 3 control scroll compressors 1 output relatively high power, when entrance 11 place's gaseous tensions are low, frequency converter 3 control scroll compressors 1 output smaller power.Scroll compressor 1 outlet 12 places are provided with over-pressure safety device, damage machine when avoiding pressure excessive and cause danger.Frequency converter 3 in above-described embodiment also can adopt Exchange Server to substitute.
The utility model so that do not interact because of the difference of pressure between each gas well, has improved the output of natural gas extraction by technique scheme, avoids occuring security incident, has reached useful technique effect.
Above is illustrative to description of the present utility model; and it is nonrestrictive; those skilled in the art is understood, and can carry out many modifications, variation or equivalence to it within spirit that claim limits and scope, but they will fall in the protection domain of the present utility model all.
Claims (4)
1. a pipe pressure controller is installed in the natural gas well, it is characterized in that, comprise scroll compressor, frequency converter or Exchange Server connect described scroll compressor by motor, and described scroll compressor one end is the gas access, and an end is outlet.
